Backscatter's new ML2 Strobe now has TTL capabilities, however in order to use that capability the housing must have the newer USB C controller. I'm sending my housing to Backscatter to have it updated so I now have the original micro connector and the spare available. If you are looking for a spare micro hot shoe connector for your UH-EPL10 Housing, and you don't plan to upgrade, now is the time to buy. Selling the used connector for $25.00, and the new, still in the package connector for $35.00. That price includes shipping to the lower 48 states. The cost at Backscatter is $59.00 plus shipping.
